THOMAS L. THOMPSON, OF VJ'ILLISTON, TENNESSEE.

FLY-FAN.

To all whom it may concern:

Be it known that I, THOMAS L. THOMPSON,

a citizen of the United States, residing at Villiston, in the county ofFayette, State of Tennessee, have invented certain new and usefulImprovements in Fly-Fans; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to fly fans, or of the class usually termedpunkas and has for one of itsobjects to improve the construction andincrease the efficiency and utility of devices of this character.

Another object of the invention is to provide a simply constructeddevice of this character which may be suspended from a ceiling andadjusted to the height of the ceiling from the floor.

Another object of the invention is to provide a simply constructeddevice which may be elevated to the ceiling when not in use.

lVith these and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and described and thenspecifically pointed out in the claims, and in the drawings illustrativeof the preferred embodiment of the invention, Figure 1 is a sideelevation of the improved device applied. Fig. 2 is an end elevation.Fig. 3 is a section on the line 3-3 of Fig. 1.

The improved device comprises a supporting frame formed of an uppermember preferably in plate form, and adapted to be attached to a ceilingof a room and spaced vertical members 11-12 depending from the uppermember, the member 11 provided with a longitudinal slot- 13, and themember 12 provided with a correspondingly longitudinal slot let. Passingthrough the slots 13-14: is a roller or bar 15, the bar being thusrotatable and slidable in the slots;

Depending from the bar 15 are two arms 16-17, and connected to the lowerend of the arm 16 is a segmental member 18, while a similar segmentalmember 19, is connected to the lower end of the arm 17. The segmentalmember 18 is supported from the arm 16 by suitable braces 19, whilesimilar braces 20 connect the member 19 to the arm 17. By this means thearms and the segmental members are. firmly united, as will Specificationof Letters Patent.

]be obvious. Extending between the segmental members 18-19 are aplurality of rods 21, the rods being preferably square transversely. Therods 21 are designed to support a plurality of fans, and any suitableform of fan may be employed, but for the purpose of illustration aplurality of ordinary palm-leaf fans are attached to the rods. The fansmay be arranged in any desired order, but for the purpose ofillustration each rod is shown provided with two of the fans, the fansof one rod being located opposite the space between the fans of the nextrod.

Pivoted to swing at 23 to the member 11 is a catch device 2 1 having aninclined lower end 25, while a similar catch device 26 is t pivoted at27 to the member 12 and provided with an inclined lower end 28. Theinclined portions -28 extend across the slots 13-1& and in the path ofthe bar 15, so that when the latter is elevated it will displace thecatch devices which will autoit in elevated position. By this means whenthe bar 15 and its attachments are elevated the catch devicesautomatically retain it in its elevated position. The swinging portionof the device may be actuated in any suitable manner, but preferably bya cord 29 leading from one of the terminal rods 21 over guide pulleys30-31 and down to a suitable fastening cleat represented at 32. Theguide pulleys 30-31 will be connected to the ceiling of the room atsuitable points, while the cleat will be located at a suitable pointupon one of the side walls of the room.

Connected at 33-3ettothebar15,preferably near its ends, are pull cords35-36 leading over suitable pulleys 37-38 and thence to the cleat 32.Pull cords 39-40 are likewise connected to the catch device 247-26 andlead thence over guide pulleys 4:1-42-A3 to the cleat 32. By this simplemeans it will be obvious that when the device is to be actuated the bar15 is located at its lowest point in the slots 13-1& and the pull cord29 actuate to cause the supporting portion which carries the fans to bevibrated upon the bar 15, as a center, the vibrations being of anyrequired length, and as rapidly as may be desired.

If it is desired to locate the fan frame at a point intermediate theslots 13-14, the pull cords 35-36 are operated and conmaticallyleadbeneath the bar and thus hold nected to the cleat to hold the member15 swinging and its attachment at any desired point. By this means thefans may be located at any point above the floor within the range of theslots. If it is desired to elevate the fans supporting portion to itsfullest extent, the pull cord 29 is actuatedto draw the member 15 abovethe catches 24.26 and in position to be engaged thereby and thusmaintained in its uppermost position.

The fan device may be actuated when in its highest position, ifpreferred, but generally the catches Will be employed only to supportthe fan devices when not in use. The member 15 may be of any requiredlength and the members 1l12 spaced at any required distancecorresponding thereto and the rods 12 may be of any required length toenable the fan area to be increased or decreased as required. Thestructure will preferably be formed of light wood, bamboo, or othersimilar material, and it is not desired therefore to limit the device toany specific material from which it may be constructed.

The device may be readily adapted to ceiling of any height withoutmaterial structural changes, as will be understood.

What is claimed is 1. In a device of the class described, supportsspaced apart and provided with longitudinal slots, a bar extendingthrough said slots, arms depending from said bar, segmental membersconnected to said arms, a plurality of rods spaced apart and extendingbetween said segmental members, fan devices carried by said rods, meansfor moving said bar in said slots, and means for said segmental membersand their connections.

2. I11 a device of the class described, a longitudinal bar arranged tobe adjusted vertically, arms spaced apart and depending from said bar, asegmental member conneeted to each of said arms, a plurality of rodsconnected between said segmental members, a plurality of fan devicesconnected to said rods, and means for vibrating said arms and theirconnect-ions.

3. In a device of the class described, supports spaced apart andprovided with longitudinal slots, a bar extending through said slots,arms depending from said bar, segmental members connected to said arms,a plurality of rods spaced apart and extending between said segmentalmembers, fan devices carried by said rods, means for moving said bar insaid slots, catch devices carried by said supports and engaging said barwhen elevated.

at. A supporting frame including spaced vertical members, a fan frameincluding laterally extending portions and connected for movementlongitudinally of said vertical members and swingingly coupled thereto,means for moving said fan frame vertically of said supporting frame, andmeans for vibrating said fan frame upon said supporting frame.

In testimony whereof, I aiiix my signature, in presence of twowitnesses.
